This invention relates to improvements in and are provided with end stops as shown at wire stripping devices, particularly pliers 37. These are bars are integral with the for skinning or stripping insulated wires jaws a1 and 42 of the U clamp 43, the said and it is the principal object of the invenclamp being jointed on the pin 22 and 60 tion to provide a device of this kind that adapted toopen and close in conjunction can either be operated at a stationary workwith the jaws of the plier element; being bench or carried on the person of a workactuated by the arc bars above described. man, as occasion requires.
